Afternoon, everyone!

Sorry to be bombarding you with so many questions today...I've been away on a work assignment for the last 2 months and haven't been able to do hardly anything!

So I'm utilizing this week to catch up on life stuff before heading back to work.
Anyway, I picked up an Lc. Fire Dance 'Patricia' today and while I was watering him I noticed that he had what I think must have been a spike or a growth that maybe died? Inbetween two of the leaves? I am new to Cattleays, so I'm not sure and I want to make sure. What should I do with it? Cut it? Leave it alone? Will it not grow anymore? (first picture)
I also have an Eplc. Golden Sunburst that has a brown sheath looking thing coming through two of its sets of leaves. They started out green and then turned this brown color (the last 2 pics)...is this normal? Is this just how Cattleyas grow? Is this new leaves or something else? Will it go away?
Sorry to ask so many questions, I am still brand new to Cattleyas. Thanks, all!
